' ELEVATOR CONSTRUCTION.

Application filed June 14,

This invention relates generally to elevator constructions and refersparticularly to a novel system of grouping the same.

In the past it has been the pract ce to group the elevators in a mannerpermitting access to all from the same level. In the construction oftall buildings where the total area of the lot is relatively small com-'pared with the height of the building, the space required for theelevators 1s comparatively great. It is therefore apparent that Valuablespace must be used for thls purpose, which might otherwise be utillzedfor office area. The primary object of the present invention is toremedy this situation to a great extent by providing a system wherebythe groups of elevators are combined in such manner as to economizespace.

Another object is to provide inner and outer groups of elevators andmeans wherebyv each group is easily accessible from the entrance floorof the building.

It is a further object to provide a means of transfer between the innerand outer groups of elevators at various floors selected.

With the above and otherobjects in view, the invention consists incertain novel features of construction, combinations and arrangements ofparts as will be more fully described and particularly pointed out inthe appended claims.

In the drawings;

Figure 1 is a vertical sectional view through a building showing anarrangement of elevators;

Figures2 and 3 are sectional views of the upper and lower loading levelstaken on lines 22 and 33 of Figure 1 respectively;

Figure 4 is a view of a transfer floor;

Figure 5 is a modified form of loading means for the elevators.

Figure 6 is a modified form of the invention shown in Figures 1 to 4.

Referring now to the drawings the numeral 10 designates a tall building,11 the entrance floor, and 12 and 13 inner and outer groups of elevatorsrespectively, the inner group comprising rows 14 and 15 and the outergroup comprising rows 16, and 17 respectively. With this arrangement alarge elevators are concentrated as a unit in a comparatively smallspace; however, because of the fact that the rows 16 and 17 practicallyenclose the inner group 1928. Serial No. 285,406.

12, it is necessary to provide separate means for permitting the loadingand unloading of each group. One means for accomplishing this is shownin Figure 1 wherein the elevators of the inner group extend to a lowerlevel than the outer group. Each group however is only one half a floorremoved from the entrance floor and the rows 16 and 17 of theo'utergroup are reached from an upper level 18, while access is had tothe rows 14 and 15 of the inner group from a lower level 19.. Forconnecting the upper level to the entrance floor, a central ramp orstairs 20 may be provided, while a pair of spaced ramps or stairs 21 and22 positionedon each side of the ramp 20 may connect the lower level tothe entrance floor.

As disclosed in Figure 1, thebuilding is shown as consisting of fortystories with the row of elevators 15 extending to the top of thebuilding and constituting the express group, while the row 14 isdesignated as the second intermediate elevators and extend to the,thirtieth floor. Each of the two outside rows 16 and 17 extend to thetenth and twentieth floors respectively and are designated as the localand first intermediate elevators.

With the arrangement as thus described, a person desiring to take eitherthe express or second intermediate elevators can reach' the same bydescending either of the ramps 21 or 22 to the lower level 19, whileanyone Wishing to take a local or a first inter mediate elevator mayascend the ramp 20 to the upper level 18.

It should be stated that applicant does not wish to limit himself to thespecific arrangement above described and that other means may beemployed for gaining access to the difi'erent groups of elevators. Forinstance in Figure 5 there is shown an arrangement in which the numeral23 indicates a ramp or stairs composed of two connecting sections 24 and25 leading to the up per level while a similar ramp 26 leads down to thelower level.

It is evident that the access and, termination levels might be ondifi'erent floors in any portion of a building or structure where such ameans of elevator communication might'be required also that any numberof inner groups could be provided with a necessary number of loweraccess levels and corresponding number of upper floor terminations; alsothat the inner group or groups could consist of one or more elevatorsand that such an arrangement might be used for passengers, freight orany purpose for Which elevators are used. j v

It is furthermore apparent that the outer group instead of consisting ofthe outer rows 16 and 17, may also include the end elevators of each ofthe inner rows so that the inner group will be entirely surrounded bythe outer group. However, it is evident that regardless of the specificarrangement of the groups, levels, and numbers of elevators, in eachinstance I have provided a novel construction which permits a greaternumber of elevators to be grouped together in a given space than hasheretofore been possible, thus releasing valuable space for otherpurposes and therefore greatly increasing the usable space of abuilding.

In order to insure the efiicient operation of the present system, it ispreferable to provide a means of transfer between any two groups ofelevators and particularly between the inner and outer groups. This isaccomplished in one manner by providing the end cars of the inner groupswith side doors so that they may stop at a transfer floor to permitaccess to and from the cars of the outer groups. In Figure 5 is shown aview of the tenth floor which in the present instance will be designatedas a transfer floor. If a passenger in one of the end express or secondintermediate cars wishes to change to the first intermediate group orvice versa, he may do so by leaving either of the first mentioned groupsby one of the side doors 27 at the tenth floor and walk around to theother group. Means may alsobe provided whereby a passenger can transferfrom one ofthe inner cars of an inner group to a car of an outer groupat the transfer floor. This is accomplished by providing passages 28between rear doors of the cars of the outer groups and the front doorsof the inner groups whereby a passenger may pass from one car to anotherby means of an enclosure passage.

Referring now to Figure 6 a modified form of the invention is disclosedin which two rows 29 and 30 respectively are shown, the former beinglocated adjacent a wall 31 of a building and the latter being positioneddirectly in front of the row 29. With this arrangement the row 29 willextend to a lower level than the row 30 for permitting loading andunloading of the elevators of the former.

While it is believed that from the foregoing description, the nature andadvantages of the invention will be readily apparent,

I desire to have it understood that I do not limit myself to what isherein shown and described and thatsuch. changes may be resorted to whendesired as fall within the scope of whatclaimed.

What I claim as my invention is:

1. In a building construction, an inner group of elevators, an outergroup of elevators adjacent to the inner group and terminating at alower level than the inner group, the space between said groups being solimited as to prevent access for passage to said inner group, anentrance floor, and passages leading from eachof said levels to theentrance floor. I

2. In a building construction, an inner group of elevators extending toa level below the entrance floor of the building, an outer group ofelevators adjacent to the inner group and terminating ata level abovethe entrance floor the space between said groups being so limited as toprevent access for passage to said inner group, a passage leading fromthe lower level, and second passage leading from the upper level andterminating with said first mentioned passage at the entrance floor. 7

3. In a building construction, an inner group of elevators extending toa level below the entrance floor of the building, an outer group ofelevators adjacent to the inner group and terminating at a level abovethe entrance floor the space between said groups being so limited as toprevent access for passage to said inner group, a pair of spacedpassages leading from one of said levels, and a single passage leadingfrom the other level and positioned between the aforesaid passages, allof said passages meeting in a common plane at the entrance floor.

4. In a building construction, an inner group of elevators, an outergroup of elevators adjacent the inner group the space between saidgroups being so limited as to prevent access for passage to said innergroup, loading means for each of said groups, and transfer means fromone group to the other at certain designated floors.

5. A bank of elevators in compact rows, means of access to one of saidrows of elevators at one grade, and independent means of access toanother of said rows at another grade, the space between said rows beingso limited as toprevent access thereto for passage to any row ofelevators.

6. A bank of elevators in compact relationship including an interiorelevator, an exterior group of elevators surrounding said inner elevatorand preventing access forpassage to said interior elevator, means ofaccess to said exterior group of elevators at one grade, and independentmeans of access to said interior elevator at another grade.

7. A bank of elevators in compact rows, including inner and outer groupsof elevat- 01's the space between said outer group being so limited asto prevent access to said inner group, said inner group of elevatorsextending below said outer group to permit loading and unloading of theformer.

8. A bank of elevators in compact rows,

including inner and outer groups of ele vators, the space between saidouter group being so limited as to prevent access to said innergroup,said inner group of elevators extending above and below said outergroup to permit loading and unloadingof the former.

In testimony whereof I afiix my signature.
